WINDOW esse AND FRAME.

To aZZ whom t may conce/rn:

Be it known that I, HERMAN RosnNZwEic, a citizen of the United States,anda resi? dent of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a newA and ImprovedlVindow-Siash .and Frame, of which the following is a full, clear, andexact description. 4

Among the principal objects which the present' invention has in vvieware: to simplify` and strengthen the construction of window frames andsashes; to avoid air drafts in the window-closing members; to facilitatethe operation of window sashes; and to facilitate the cleaning of saidsashes.

' Drawings.

Figure 1 is a side view of a Window, having sashes and framesconstructed and arranged in accordance witlfi the present invention;

Fig'. 2 isa detail view showing in perspective a fragment of windowframe and of a sash mounted therein, the sash being shown as pivoting onone of its guide members; Fig. 3 is a cross section on an enlargedscale, the section being taken as on the line 3-3 in Fig. 1;

Fig. 4 is a detail view in perspective sho-wing a lock strip with whichsashes constructed in accordance with the present invention areprovided;

Fig. 5 is a detail view of a clamping screw for moving the lock stripsto engage or disengage the guide members, and for locking the samefixedly in correspondence therewith.

Descrip tio/n.

As seen in the drawings, the window sashes constructed and arranged inaccordance with the present invention have stiles as indicated by thenumeral 10, constructed from a single piece of metal bent in the form asshown best in Fig. 3 of the drawings, to provide a seating channel 11and a pocket 12 for a locking strip 13. The rails 141 of the sash areconstructed yin a similar manner except that the pocket 12 is not formedtherein.

The sashcs are pivoted by a double-headed rivet 15 to a guide member 16.The member 16 has at one edge, a guide flange 17 SI5ciiatimiy ofLetters. @ateat- Applicaton filed September 22, 1916.

formed by closely lapping the metal on itself. On the opposite edge, themember 16 has a guide. iange 18, which in conjunction with aV frange 19,forms a pocket 20, which in ser-vice registers with the pocket 12 and isadapted to receive the strip 13 when the same is, moved laterally fromthe pocket 12.

Zhen the strip 13 is moved into the pocket 20., the sash is held innon-rotative relation to the member 16. rlhe screw 21 which threaded ina perforation formed in the strip. 13, may now be manipulated to clamp.the metal of the stile between the said strip 13 and the wing nut head22 of the said screw. Each stile has two screws havingheads 22.

Then itis desired to rock the sashes on their pivots 15., this is doneby preliminarily releasing the screws 21, and thereby relieving thefrictional clamp on the strip 13, which per-mits the same to beretracted into the pocket 12 to free the pocket 20.

It 'will be seen that in the above-mentioned position, the sashes may beswung on their pivots irrespective of the position they occupy in theframe. Of course it will be understood that the opposite sash is removedfrom interference with the frame which is to be pivoted. Attention isdrawn to the fact that this arrangement permits the upper sash to beopened to swing on its pivot while the lower sash is closed.

The frame has stiles 23 constructed of sheet metal which is bent to formin the face of the stile, two sets of grooves 24. The grooves 24: areseparated a distance approximately the thickness of the sashes and thewidth of the members 16, and are arranged to receive the'llanges 17 and18 of the members 16. By reason of the fact that the grooves thus formedare disposed as shown, it is' obvious that the tortuous passage betweenthe surfaces of said grooves and the surfaces of the flanges 17 and 18,forms a wind or weather break. This function is augmented by the hollowspaces 25 formed between the members 16 and the faces of the stiles Theestablishment of a minor expansion chamber thus between the outside andinside pressures operates to check the passage of the air through thefirst of the second groove. As the pressure on the eX- tcrior is itfulit does not gain admission to the inner grooves 24.

A similar effect to that above described is performed by the strips 13which bridge across the junction of the stiles l0 and members 16 to forma varying wind break therefor.

To cover `the openings of the slots 26 formed in the stiles 10 for thescrews 21, there are provided covervplates 27 which are permanentlysecured to the screws 21.
